This TOWER 22mm 3 Port Mid-Position Valve (VAL322MP) is designed for homeowners with fully pumped central heating systems seeking precise control over hot water and heating zones. Its key benefit is the ability to direct water flow independently to heating, hot water, or both simultaneously, optimizing comfort and energy efficiency. A potential caveat is its requirement for specific system wiring and compatible thermostats/programmers to function correctly. This valve offers reliable spring return operation and standard 230V AC switched output.

Check the 230V AC power supply to the valve. Verify wiring connections to the programmer, room thermostat, and cylinder thermostat are correct and secure. Ensure the system is calling for heat or hot water.
Ensure the 22mm compression fittings are tightened correctly. If leaks persist, the fitting may need to be re-made or the valve may need replacement.
Confirm that the system's programmer and thermostats are set correctly. Check that the valve is receiving power and that the actuator is moving. If the valve is stuck, attempt to use the manual override lever.
Some noise during operation is normal. Loud grinding or clicking may indicate an obstruction or a failing actuator. Check for any external blockages or signs of damage.
Setup: This valve is designed for fully pumped central heating systems. Ensure power is isolated before beginning installation. The valve connects to the heating and hot water pipework using the 22mm compression fittings. Wiring should be carried out according to the system's specific requirements, connecting to a compatible programmer, room thermostat, and cylinder thermostat. The valve requires a 230V AC power supply.
Compatibility: Compatible with standard 230V AC central heating control systems. It requires the presence of a system pump and must be wired with an appropriate programmer, room thermostat, and cylinder thermostat.
Care: Regularly check for leaks around the compression fittings. The external casing can be wiped clean with a dry or slightly damp cloth. Avoid using abrasive cleaners. Periodically, verify that the manual lever operates smoothly. Ensure the area around the valve is free from dust and debris to prevent internal mechanism issues.
